TO PREPARE PATTIES, COMBINE TURKEY, CHOPPED FENNEL, ONION, MUSTARD, SALT, LEMON-PEPPER, GARLIC AND BBQ SAUCE, HANDLING MEAT AS LITTLE AS POSSIBLE TO AVOID COMPACTING. DIVIDE TURKEY MIXTURE INTO SIX EQUAL PORTIONS. MOISTEN HANDS WITH OLIVE OIL TO FORM 6 PATTIES. (PATTIES SHOULD BE LARGE ENOUGH TO FIT SESAME BUNS). BRUSH GRILL WITH OIL. GRILL PATTIES ON MED/HIGH FOR APPROX 6 MINUTES. TURN PATTIES AND CONTINUE GRILLING FOR ADDITONAL 6-8 MINUTES OR UNTIL MEAT THERMOMETER READS 170 DEGREES. DURING FINAL MINUTE OF GRILLING, PLACE EQUAL AMOUNTS OF SMOKED GOUDA ATOP EACH PATTIE. PLACE SESAME BUNS, CUT SIDE DOWN ON GRILL TO TOAST, WATCHING CAREFULLY TO AVOID BURNING. WHEN CHEESE IS MELTED AND BUNS ARE TOASTED, REMOVE PATTIES AND BUNS FROM GRILL. TO BUILD BURGERS, PLACE ONE SLICE MANGO ON CUT SIDE OF BOTTOM HALF OF EACH SESAME BUN. PLACE ONE PATTIE ATOP EACH MANGO. PLACE EQUAL PORTIONS OF BACON ATOP BACON (APPROX. 3-4 SLICES PER PATTIE). PLACE EQUAL AMOUNT OF GRILLED ONIONS ATOP BACON.
